Description Robert Hogan 2012-06-20 13:08:09 PDT
These two fail on Qt only. The diff provided by Qt's ImageDiff is not very informative so I've attached one using Chromium's. There's a 1-pixel high line of difference at the bottom of the test block. The tests run fine on other ports so there must something Qt-specific at work here. It's safe to skip for now as there is coverage in other ports but it would be nice to understand what the difference at work is here.

These tests introduced in http://trac.webkit.org/changeset/120844 and fail only on 32 bit Qt platforms (Qt 4.8, Qt 5.0 WK1 and WK2 too) I cc-es Zoltán, our 32/64 bit debuger expert. Have you got any idea? I'm going to skip them until fix to paint the bots green.
